Nitori Futon Drying Sheet / Futon Drying Cover Purchased several years ago, used once or twice. Although there is no noticeable damage, it has been stored and inspected at home by an amateur. I would be grateful if someone who understands this would use it. It will be compressed for shipping. The approximate size is 160 x 240, so I think it can be used for single to double futons. Upon closer inspection, there was one stain on the outer bag (see image three). Please understand.
